TX becomes unresponsive after some time

TX becomes unresponsive after ~2h of use, 100% CPU on one core

I'm using TrackAudio 1.3.3 on Manjaro Linux (kernel 6.14), and I'm encountering an issue where TX becomes unresponsive after extended use (~2 hours).

Symptoms

• I can still hear other pilots clearly
• Pressing PTT does not reliably highlight the active TX frequency in the UI (sometimes only after a delay)
• Pilots report that their callsign is missing from my transmissions
• Eventually, I am unable to transmit at all
• htop shows one CPU core at 100% usage caused by the TrackAudio process

Affected versions

This behavior occurs with both:

• the trackaudio-bin AUR package
• and the official AppImage

Temporary workaround

Restarting the application restores TX functionality — but only temporarily.

Additional observations

The log file at
~/.local/state/trackaudio/trackaudio.log
continues to record PTT input events during the broken state.

Version history

I'm not sure if this problem also existed in previous versions.
I recently switched from Windows to Linux, and my only session on version 1.3.1 was likely too short for the issue to occur.

Let me know if I can provide more logs or test a debug build.

Have you ever had this issue on Windows, or purely on Manjaro? Sounds like there might be a memory leak on this platform and I know where this could come from.

No, windows worked (and works) fine. A memory leak might be the case, although the memory footprint only rises by a few hundred megabytes. Do you need some more info?
